Really great design, nice and clean, easy to fit and blends into the bike.

Good price and quick delivery

worked a dream!

Such a simple fix to attach a rear rack. Completely inconspicuous when not in use.

Bought as a spare while i have my oem clamp color matched to my bicycle accent color. Diverge comp carbon specifies 30.8mm, this is 30.6mm and fits fine. Also opens up the possibility of using a rear rack eventually since the frame does not have eyelets for racks on the seat stay.

Without this collar I would not have been able to mount my rear rack.

Perfectly engineered, strong, lite, efficient. Good description, uber quick ship, and good value as usual.

Great option for attaching a Tumbleweed rack to my Diverge. Only issue I ran into was the bolts that came with the rack were too long to go into the collar and I had to purchase bolts that were shorter.

I purchased this seat collar to be able to add a rack to my Creo SL Expert. This was easy to install and works really well allowing my rack to mount to the seat collar.

I needed this so I could attach a rack to the back of my bike. It works perfectly!
